We want to show how blubber keeps animals warm.We fill a container with ice cubes and water then in a plastic bag some vegetable oil and cotton.Finally we put both hands, one in the oil and one into the ice water.They all agreed that one hand was freezing and their hand in the oil was warm.

We also looked at some ideas for experiments for younger children. I have posted the links to ppt documents in case you want to translate them into Spanish. They relate to the activities in the powerpoint show above.

Parachute men, cabbage jelly, flying seeds, sunlight energy, puddles, fast cars, floating boats, robotics and different materials. I hope these are useful!

Hello All,
I've not forgotten about my Blog, I've just been very busy at work and I teacher older children. I have however continued writing and I have become a big fan of Level Assessed Tasks. Here is one for early secondary that I have written:Link to pdf: Particles and phase changes
Here is another more sexto one: from TES:

I think they are great because students can choose how much or how little they do and they are really easy to grade, just tick off the parts that they have done. If you have any requests, I am now very fast at writing these.

There are loads of this style of task worksheet available on the internet.

Milk is made up of minerals, proteins and fats. When the dish soap enters the milk, the fat begins to break up. The soap molecules run around and try to attach to the fat molecules in the milk.The fat and proteins are super sensitive to changes in the milk and so when the dishwashing liquid is added a chemical reaction occurs. The soap and fat work to join together, which causes the movement. Normally this process would be invisible to you, but the food coloring helps you to see all of the movement taking place.

Coins were traditionally made from a bronze alloy of copper, tin and zinc. Lately, they have been made from copper-plated Steel; so the new copper-plated steel coins are attracted to magnets. The iron content in the steel core is what makes them magnetic.

Not all rocks sink.Pumice floats on water because it´s formed due to quick cooling of lava on the Earth Surface.
It has many holes in it (gases trapped inside when it was being formed.)
It is full of bubbles and it has less density.

The experiment works because the liquids used have different densities. The liquids with higher densities weigh more than the liquids that are less dense. So the less dense liquids will sit on top of the denser liquids.

Carefully add a layer of shaving cream to the water.The shaving cream represents a cloud and the water is the atmosphere.
Simply add a few drops of blue food colouring to the shaving cream. The weight of the food colouring will start to push through the shaving cream and fall down through the water; (the darker grey clouds were heavy with water droplets or rain, the food colouring.

If you put a can of regular coke or pepsi into a container with water, it will sink. While, if you put a can of diet coke into the same container, it will float.

WHY?

Coke has more mass because of the 35 grams of sugar it contains, compared to the 125 milligrams of sweetener in a can of diet coke.

The cans of soda have exactly the same volume, or size. But their density is different due to what is dissolved in the soda. If you look at the nutrition facts on a can of regular soda, you will notice that it contains sugar...a lot of sugar.
